Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, and particularly to a photovoltaic module paving device. Background Art

[0002] In recent years, with the strong promotion of clean energy, photovoltaic power generation has also seen rapid development. In the process of industrial application, photovoltaic modules are the basic components of photovoltaic power generation. In a 100-megawatt photovoltaic power station, the number of photovoltaic modules is at least more than a hundred thousand. To build a photovoltaic power station, it is necessary to assemble such a large number of photovoltaic modules into photovoltaic matrices in an orderly manner on site. It can be seen that the workload is huge. At present, large photovoltaic power stations use large photovoltaic modules. For convenient transportation, multiple modules are packaged as a whole in cartons. Among them, the large module size is 2384X1303X35, and the weight reaches 38.7 kg. The height of the photovoltaic bracket for installing photovoltaic modules is ≥ 1600 mm at the back. Generally, 5 - 6 workers are required to cooperate. First, the modules are carried to the photovoltaic bracket, and then the position is adjusted to install and fix them with screws. The whole process depends entirely on manual labor, with low efficiency, great potential safety hazards, and it is very easy to cause hidden cracks in the modules during the handling and installation process, resulting in the scrapping of photovoltaic modules. At the same time, since large photovoltaic power stations are generally built in the deserts and gobi in the northwest, the photovoltaic matrices will be built according to the terrain undulation, resulting in height differences between adjacent photovoltaic matrices, and the ground has problems such as sandy land, unevenness, and easy subsidence. This requires the equipment to have good passability and ensure stability during paving to avoid phenomena such as hitting and knocking the boards. And currently, ecological photovoltaics and economic benefits are emphasized, and there are photovoltaic projects such as agricultural-photovoltaic complementary, resulting in the increasing height of photovoltaic brackets. The lower edge of some photovoltaic matrices is even more than 2 meters above the ground, which makes the paving range of the equipment change greatly and increases the technical difficulty.

[0003] At present, the assembly and laying of photovoltaic modules mostly rely on manual labor, which is inefficient and costly. At the same time, it is affected by various factors such as construction sites, climate conditions, and labor costs, resulting in the assembly of photovoltaic modules becoming an inevitable problem in newly built photovoltaic power stations. Since the specifications of photovoltaic modules are determined and the installation forms are unified, it is possible to replace manual labor with equipment and improve the assembly efficiency. At the same time, to solve the problems of handling, placing, and positioning of large and heavy photovoltaic modules; uneven and easy-to-sink ground; high and low photovoltaic brackets and high installation height; improving assembly efficiency and reducing losses during installation.

The lifting connecting rod 62 is driven by the lifting cylinder 63 to lift the forklift 66, and at the same time, the forklift 66 is driven to tilt by the tilting cylinder 61.

[0037] Working principle: As Figure 1 shown by the whole machine composition, the wheeled chassis 1 provides a bearing platform and power, realizing walking, operation, and transfer; the power system 2 and its accessories are the power sources of the whole machine, and an engine or a power battery can be carried as the power source; the control system 3 is divided into an electrical control system, a pneumatic control system, and a hydraulic system. The electrical system is responsible for the control of the whole machine, the position sensing of the working device, and visual positioning, etc. The pneumatic control system is responsible for the braking of the whole machine and the vacuum suction and pick-and-place of the photovoltaic module by the working device. The hydraulic system provides a power source for the working arm and the feeding mechanism; the rotating platform 4 can rotate 180° left and right, providing a control space for personnel and expanding the operation range of the working device; the operation range of the industrial robot is expanded by adjusting the position of the working arm. The industrial robot 56 realizes functions such as material handling, placement, and positioning. Precise positioning of the photovoltaic module is achieved through the feedback of various sensors installed on the robotic arm and the industrial robot; the feeding mechanism 6 is arranged at the front end of the equipment. After the photovoltaic module packaged as a whole is fork-lifted through the hydraulic system and the electrical system, it is lifted and tilted to a suitable height, so that the glass surface of the photovoltaic module is exactly upward, which is convenient for grasping and placement.

[0038] As Figure 2 shown by the wheeled chassis 1, according to Figure 1For the overall layout of the whole machine, the overall weight will tend to concentrate at the front end. It is necessary to adjust the chassis wheelbase according to the axle load to balance the axle loads of the front and rear axles. A differential lock is set on the rear axle, and a tire 13 is installed on the axle. A floating oil cylinder 12 is set between the axle and the frame to switch between the floating and rigid states of the chassis platform. A rotary drive 14 is set above the frame platform 15. Through these customized designs, the chassis has improved passability, increased ground contact ratio, increased overall machine width, and the chassis platform is not affected by terrain fluctuations, providing stability for the deflection operation of the rotary platform;

[0039] Such as Figure 3 、 Figure 4 The feeding mechanism 6 is arranged at the front end of the equipment. The forklift loading process is similar to that of a forklift. The operator controls the movement of the vehicle to pick up the materials. Among them, the lifting oil cylinder 63 is responsible for lifting the materials, and the tilting oil cylinder 61 is responsible for tilting the materials 90° after they are lifted in place. The inserted materials are limited by the limit and the second guardrail 64 to prevent them from falling, shifting during the tilting process. Sensors are set on the forklift forks 66 to feedback the position status of the materials. The principle of the feeding mechanism is a parallelogram mechanism, which can always keep the materials in a horizontal state during the lifting and tilting processes, reducing the grasping difficulty of the working arm and avoiding the sliding of the photovoltaic modules at the same time; Figure 3 This is the forklift loading state of the feeding mechanism. The state of the lifting oil cylinder 63 can be controlled to adjust the tilting position of the forklift forks 66 for easy loading of materials; Figure 4 This is the state where the lifting and tilting of the feeding mechanism 6 are in place. Through tilting, the front side of the encapsulated photovoltaic module 52 faces upward. The state of the tilting oil cylinder 61 can be controlled to adjust the regulation between the forklift forks 66 and the horizontal position by ±5°, for easy grasping by the working arm. The control of the lifting height can effectively reduce the reciprocating stroke of the working arm grasping and improve the operation efficiency;

[0040] Such as Figure 5 As shown, the rotary platform 4 can rotate 180° with the rotary drive on the chassis to expand the operation area; at the same time, the rotary platform 4 is arranged with the electric control box of the industrial robot 56, the air tank of the vacuum air circuit system, various electrical components, the control and operation platform provided for personnel, and the installation position of the working arm; As Figure 5 shown, the working arm will extend out of the platform to expand the operation range, and the weight of the industrial robot 56 is about more than 1 ton. To ensure the stability during operation, a counterweight of about 2.5 tons is set on the rotary platform assembly 44, so that the vehicle can operate stably in the state of tilting 10° to the left and right; As Figure 5 shown, a driver's seat is provided. The operator can sit on the driver's seat to control the equipment. When the rotary platform returns to the correct position, the vehicle movement and transfer can be controlled. When the rotary platform rotates 90° on both sides, the industrial robot 56 can be controlled to perform the paving operation, and the driver's seat is close to the operation area without line of sight obstruction and has a wide view;

[0041] Such as Figure 5The working arm of the working device 5 shown is driven by the boom cylinder 50 to achieve the up and down swing of the working arm. A sensor is set on the boom 58 to feedback the position of the working arm, providing position feedback for automatic paving; As Figure 5 shown, the grasping, handling, placing and positioning of the photovoltaic module are jointly completed by the industrial robot 56, the suction cup 51, the suction cup bracket 53, the pneumatic control box 55 and the sensor bracket 54; To ensure reliability in grasping the photovoltaic module and avoid damaging the module during grasping, a suction cup 51 with buffering is adopted, and a sensor is set on the suction cup bracket 53 to check whether the grasping process is secure; A special section of the working arm is designed to expand the working range of the industrial robot, enabling the working range of the device to be compatible with the range from 500 - 2600 from the ground at the lower edge of the photovoltaic matrix, effectively expanding the usage range of the device, and at the same time greatly reducing the dependence on the working radius of the industrial robot 56, significantly reducing the procurement cost of the industrial robot; Secondly, the triangular design of the working arm has stability and can ensure that the installation platform 57 always remains horizontal, which can minimize the zero drift of the industrial robot caused by vibration and jitter during operation.

[0042] As Figure 6 shown, according to the working range, adjust the dimensional parameters of the working arm to match the working radius of the industrial robot 56. Within a certain working range, keep the working arm stationary, and rely on the working range of the industrial robot 56 itself to achieve the paving operation of the photovoltaic module 52; To achieve automatic paving, the position of the working arm can be preset according to the ground height of the lower edge of the on-site photovoltaic matrix. Relying on the control program, working accuracy, position sensing, and working radius of the industrial robot 56 itself, the photovoltaic module is grasped, handled, paved, and positioned, thus greatly reducing the difficulty of automatic control.

[0043] Especially, the mature technical solution derived from engineering equipment enables the device to consider comprehensively from the components, laying a good foundation for the stability requirements during the automatic operation of the industrial robot 56, avoiding the detection drift of various position sensors caused by the vibration and assembly clearance of the device, and providing technical conditions for precise positioning and bolt fixing during the paving of the photovoltaic module 52; Secondly, this device effectively improves the working efficiency, and it can be measured that each paving operation can be achieved in 90 seconds; At the same time, it greatly reduces the labor intensity of workers and avoids potential safety hazards such as climbing and lifting.

[0044] Especially, it is configured with remote control operation and driver's seat personnel control. Through the short-range control remote controller, the movement of the vehicle, the feeding mechanism 6, the rotating platform 4, the working arm, the industrial robot 56, etc. can be controlled, realizing semi-automatic operation during the installation process, which is convenient for point-by-point control of precise positions.
